POWER OIL CAN.

Application led. April 28, 1924. Serial No. 709,648.

T all whom t may concern Be it known that I, CLAnKsoN Gr. HAwoRrH, a citizen of the United States, residing at Russiaville, in the county of Howard and State of Indiana, have invented certain new and useful Improvements in a Power Oil Can, of which the following is a specification.

This invention relates to improvements in oil cans.

The primary object of this invention is the provision of a power oil can having air pressure feed for the lubricant thereof and improved valve means for regulating the feed of lubricant from the can according to the grade of lubricant used.

A further object of this invention is the provision of an improvement in valve regnlating means for the control of lubricant -iiow from oil cans and the like.

Other objects and advantages of this invention will be apparent during the course of the-following detailed description.

In the accompanying drawing, forming a part of this specification, and wherein similar 'reference characters designate corresponding parts throughout the several views,

Figure 1 is a cross sectional view taken through the improved oil can, showing operating details thereof.

Figures 2, 3 and 4 are cross sectional views showing different operating positions of the valve means embodied as a novel feature of this invention for the control of lubricant flow from the oil can.

Figure 5 is a view showing an improved detail of the valve regulating means.

In the drawing, wherein for the purpose of illustration is shown only a preferred embodiment of the invention, the letter A may generally designate an oil can which may consist of a container B; means C for building up a pressure within the container B; a novel spout structure D; control valve means E in the spout D; and operating means F for the valve E.

B, and preferably in the cylindrical body portion 10, a lateral extension is provided, in which an outlet opening 21 is formed and through which the oil or lubricant may flow from the container compartment 13 into the spout D, as will be suhsequently described.

Referring to the means C for building up pressure within the container B, the same includes a lateral tubular extension 25 supported by the container body 10 adjacent the bottom 11, and in a horizontal relation, which provides a passageway 26 communieating with the compartment 12. In this tubular portion 25 a needle valve 28 is provided, which has a tapered end 29 operating against a seat 30. A vertical pump cylinder is supported by the tubular extension 25,

and at its upper end is braced by means oi? a horizontal arm 36 formed rigid with the container B at the upper end thereof, and so that the axes of the container B and the pump cylinder are parallel. The pump cylinder 35, in effect, provides a handle by which the operator may grasp the oil can for the purpose of handling the same. In the pump cylinder 35 a plunger 36 and reciprocating rod 37 are provided, and the rod 37 at its outer end has a thumb or hand enga-ging head 88 thereon which the operator may force downwardly or upwardly for the purpose of reciprocating the plunger 36 in the cylinder 35. to build up air pressure within the container B when the needle valve 2S is open.

Referring to the spout structure D, the same is novel, and is exteriorly supported upon the container B. It includes the main tubular portion '10, which at the lower end thereof rests within a suitable socket opening 4:1 provided by the lateral extension 20, so that the outlet opening 21 at the lower end of the container B is-in communication with the vertical passageway 42 extending through the spout iortion 40. The upper end of the containerv may be provided with `a lateral extension 45 engaged about the spout portion 40 for the purpose of supporting the spout portion 40 in exterior parallel relation with the container B. The spout portion 40 extends upwardly above the container B for any desired height, and prefcrably at its upper end supports the novel valve structure E. A swivelly mounted J- shaped nozzle portion 48 may be considered a part of the spout D, the same being swivelprovided through t-he swivel nozzle 48.

ly supported by the valve structure E, as will be subseauently mentioned.

Referring to the novel valve structure E, the same includes a housing portion 50, providing a passageway 5l therethrough which aligns with the passageway 42 of the spout portion 4G and also with the passageway 5&3 valve member is supported in the housing or casing 50, 'transversely of the passageway 5l, and lproviding a transverse port 56 therethrough which may be aligned to any ldesired degree with the passageway 5l to selectively' control the flow of lubricant of any desired grade or quantity. The valve member 55 at one outer end 'thereof is preterably squared, as at 58, and on this squared portion a. lever plate or arm is Xed; said arm or plate 60 being provided at its outer end with a series of openings 6l, 62, and 63 arranged in concentric alignment with the valve axis, and with which openings 'the operating mechanism F may be selectively connected, as will be subsequently described.

At its upper end the valve casing 50 may detachably support a coupling' 65 which is used for the purpose of swivelly connecting the nozzle piece 48 in the relation illustrated and Vdescribed with respect to other details of the spout D, and so that the end of the noz- Zle 48 may be turned in any desired direction for 'the purpose of accessibly reaching Vany desired machinery or part of machinery to be lubricated.

Referring to the means F for operating the valve structure E, the samepreterably includes an operating` lever pivotally connected intermedia-'te its ends upon a pin or screw 7l, the latter being supported upon an extension 7 2 formed rigid upon the top l2 of the container B. One end of the. Ahandle 70 extends toward 'the means C for engagement by the thumb of the operator, and the opposite end portion 73 extends toward the spout D and is provided wi'th a 'series of openings 74, 7 5 and 7 6 therein. A connecting rod 78 is provided as part of the means F, the lower end ot which may be selectively connected in any of the openings 74, 7 5 or 76, and the upper end of which may he. selectively connected in any of the openings '6l, 62 or 63. A spiral spring 79 normally connects the end 73 of the lever 70 1 with the lateral extension 45 of the container B ior the purpose of pulling downwardly upon the connecting rod 78 to normally close `the valve E to prevent accidental ilow of it can readily be understood that it will he advisable to permit opening ot' the valve E to a relatively full extent to permit flow of heavy or viscid lubricant from the oil can. In this event the connecting rod 78 at its upper end may be connected in the lowermost opening 63 of the valve arm 60, and 'the lower end of the connecting rod 78 may be connected in the outermost opening 76 o't the operating lever 70. The spring 79 upon the occasion of such connection of the parts normally tends to draw the valve into 'the closed position illustrated in Figure 2 of the drawing. However, upon full depression of t-he lever 70 until the 'free end engages top l2, the operator will force the arm 60 upwardly as is illustrated in Figure 3 to fully align the valve portJ 55 with the passageway 5l through the valve, to permit maximum flow of lubricant under pressure from the oil can. a relatively light grade of lubricant 'through the oil can, the ripper end of the rod 78 may be connected in the opening 61 ot' the valve arm 60, and if desiredl the lower end of thev connecting rod 7 8 may be connected in the opening 74 of the operating When it is desired to feed lever 70, and when in its fullest open posi- Y tion the valve E will 'then assume somewhat the relation illustrated in Figure 4, so that a relatively small passageway of the lubricant through the port 56 of the valve member 55 is permitted. Intermediate regulation of the valve structure -for maximum feed of lubricant according 'to the quality of lubricant may be provided, merely-by adjusting the position which the connecting rod 78 may have with respect to the arm 60 and tothe outer end 73 ofthe lever 70.

From the forego-ing description of this invention it is apparent that an oil can has been provided which includes a pressure feed of the lubricant therefrom :mrl novel features of lubricant control.

Various changes in the shape, size, and arrangement of parts may be made to the form ot invention herein shown and described, without departing from the spirit ot this invention or the scope oit 'the claims.
